Fig. 3 is a sectional view taken through the burner box at right angles to that of Fig. 2.

Fig. 4 is a perspective view of the burner box with the burners removed and illustrating in dotted lines the removability of the burner box.

By referring to Fig. 1 it will be noted that the portion of the stove to the rear of the burners, and which constitutes a part of the back of the stove, is provided by a suitable panel I, and the stove may have an oven disposed to one side of the burners, the insulation for which is shown at 2. The wall structure to the rear of the oven is illustrated at 3. A plate or panel 4 may extend upwardly at the rear of the stove. The present invention is applicable to a stove of the cabinet type wherein the top surface of the oven and of thegrating-orcover- OVGIftllC burners are substantiallypinthe same horizontal plane; also the invention is, applicable? to"v a"stove in'which; the: oven isr positionedf'above the burners and grate either inwhole or. in part.

One end-of. the stovefmay be-constituted' by:the panel 5, and thefront ofi'thestove adjacentthe burnersmay be-- provided by a panel 6; This i panel 6 may house the usual' gasmanifoldfi'l'? which-isfconnected to'a gas' supply pipe--8,- and Valve controls Gamay be exposed over "the surface i of the'panel 6: Aicorner stripsis' illustrated at I 9;. and. a spacer rstrip or'rmouldin'g is'illustrated at I I oneon each: end of the panel 62 It is. not deemed necessarysto describe rthe structural pieces at ther corners andat-otherplaces for uniting the panels and strips-'- as this" structure: is; subject to: large variationinsofarw as." the? present invention" is concerned.

The? burner box may-:b'e bounded "by a panelor 0 strip: I 5? atftheupper end. edge ofitthetstove; a sim:# ilar panel 1552? the. front,.andfa'=panel or moulding". like formatiomllat one side; The rear-ofithe burnerbox inrgeneralmay. be'defineda'by a'pan'el '2 I8, and the.parts:-I'5;-.I 6,: I .I; and: I BF-may. comprise a one-piece construction or may be fabricated from separatespiecesx A. number of burnerstareshown' at 20; some" are "shapedrdifierentiy than others, eachi'having'? asburn'erpipeleading thereto, as 'illustratedati'zi .36 Burner: supporting; devices are illustrated. at 221". upon'which thezburnersrmayirest; as illustrated in" Fig; 32' A :pilot lightttypeiofr-lighter is illustrated; at .24.; Positioned -below theburners is theiusual drip pan ortray'25 which'ispreierably removable from the front' ofl the-stove as-by: means of a;han= 4 dle 26, and this drip pan or tray may be supported on ledges 21.

The burner box proper may and preferably does consist of a unitary element, composed of an in- 40 tegral piece of material such as porcelain enamel ware, or of a number of pieces fabricated into a unitary piece, and the same is generally indicated at 30. It is designed to be positioned so as to surround the burners andconstitute a burner box, and its lower portion may be flared or curved inwardly as at 3|, so as to bring its lower edges within the confines of the tray 25. For the purpose of supporting the burner box suitable ledges or supportinig shoulders 32 may be provided. Some of these ledges may be integrally formed with other elements, as for example, the border panels I5, I6, and I1, while one of the ledges may be a separate piece positioned near the rear panel I 8. However, the particular manner in which the supporting ledge is provided is subject to variation. The burner box at its upper edge may have an outwardly extending part or parts such as a peripheral flange 35 which is adapted to rest upon the ledges 32. If desired, a cover 36 may be provided for covering the burner box structure. This may be removable when it is desired to use any one of the burners. The cover 36, instead of being entirely removable, may be connected as by means of a hinge or pintle 38 so that it may be swung out of the way. The cover 36 is particularly preferable in a so-called cab inet type of stove where the top surface of the oven lies generally in the same plane as the top surface or grate of the burner box. The grate over the burner is illustrated at 31, and this advantageously is supported by the ledges 32. The grate may be rested upon the peripheral flange 35 of the burner box 30, as illustrated in Figs. 2 and 3.

Fig. 4 shows the burner box in dotted lines, illustrating the same removed from its operative position. One Wall of the burner box, such as in the present instance the forward wall, is cut away or notched as illustrated at 39. This notch is preferably properly positioned for the purpose of accommodating the burner pipes 2|. Fig. 2 illustrates how the burner pipes are accommodated by the notch 39.

The structure, as will have been noted by the above description, embodying the support for the burner box and the grate, and the burner box structure, comprises a relatively simple arrangement. In case it is desired to clean the burner box and other adjacent parts, the grate may be easily lifted out of position assuming, of course, that the cover 36 has been previously moved to inoperative position, and then the burner box proper may be lifted out of its operative position, as illustrated in Fig. 4. This may be done without disturbing the burners. The burner box 36 may then be easily-cleansed. Furthermore, the

removing of the burner box proper makes more accessible other burner box structure and interior parts around and adjacent the burners.

I claim:

1. In a cooking stove structure having a plurality of separate burners, a box structure surrounding the burners, an open grate over the burners exposing the burners and structure below the same to view and a tray below the burners for catching dropped material, said box structure having inwardly extending ledges; and a bottomless burner box proper adapted to be inserted into the said box structure through the top thereof to surround the several burners, the walls of the burner box proper immediately surrounding the burners and permitting unrestricted flow of air past said burners, the upper edges of the walls having outwardly extending members adapted to rest upon the inwardly extending ledges, the said walls of the burner box proper having lower portions which lie above and within the outer edges of the said tray whereby to direct material into the tray.

2. In a cooking stove structure having a plurality of separate burners, a box structure surrounding the burners, an open grate over the burners exposing the burners and structure below the same to view and a tray below the burners for catching dropped material, said box structure having inwardly extending ledges; a bottomless burner box proper comprising walls for immediately surrounding all the burners and adapted to be removed from the box structure without removing said burners and permitting unrestricted flow of air past said burners, said walls having outwardly extending flanges adapted to rest upon the said inwardly extending ledges, said Walls being fashioned to curve inwardly so that their lower edges lie within the area of the tray and define an opening at the bottom of the burner box proper of smaller dimensions than the opening at the top thereof, said flanges being adapted to lie underneath the grate, and one wall of the burner box proper being cut away to provide an elongated recess for the accommodation of burner pipes leading into the said burner box proper.

3. In a cooking stove the combination of a burner box structure, inwardly extending ledges thereon, a plurality of separate burners therein, burner pipes leading into the box structure, a burner box proper having side walls for immediately surrounding the burners and being open at top and bottom and permitting unrestricted flow of air past said burners, the top of the said walls having outwardly extending flanges disposed upon the inwardly extending ledges, a tray underneath the burners, the bottom edges of said walls lying within the area of the tray for directing dropped material thereinto, one wall of the burner box proper being cut away to form an elongated notch for the accommodation of the burner pipes, and a grate resting upon said inwardly extending ledges above the burner box proper and exposing the burners and the burner box proper to view, said burner box proper serving to conceal the walls of the said box structure and being readily removable through the top of the said box structure without removing said burners.
